Temperature monitoring

Older pSeries systems (Power4) are equipped with environmental sensors. You can read the sensor values using:

# /usr/lpp/diagnostics/bin/uesensor -l
You can use these sensors to monitor your systems and your computer rooms. It isn't very difficult to create a script to monitor these environmental sensors regularly and to display it on a webpage, updating it automatically. Newer systems (LPAR based) are not equipped with these environmental sensors. For PC systems several products exist, which attach to either a RJ45 or a parallel port and which can be used to monitor temperatures.

UNIX Health Check delivers software to scan Linux and AIX systems for potential issues. Run our software on your system, and receive a report in just a few minutes. UNIX Health Check is an automated check list. It will report on perfomance, capacity, stability and security issues. It will alert on configurations that can be improved per best practices, or items that should be improved per audit guidelines. A report will be generated in the format you wish, and the report includes the issues discovered and information on how to solve the issues as well.
